clouds of gas and dust
100
Swollen cool star
What is a Red Giant?
100
A shell or shells of gas ejected by a relatively low-mass star that is in the process of dying, and becoming a white dwarf.
What is a Planetary Nebula?
100
A region of space where gravity has warped space-time so much that straight lines have become circles.
What is a Black Hole?
100
A telescope in which the light is collected (and reflected) by a mirror.
What is a reflecting telescope?

What happens as the star is compressed?
the star heats up?
200
The constellation home to Betelgeuse.
What is Orion?
200
Double Jeopardy! Brief event which generates a huge amount of gamma-ray energy, lasting from a fraction of a second to a few minutes. Such bursts are now thought to come from rare, extremely violent events in other galaxies.
What are Gamma Ray Bursts?
200
The collapsed, hot remnant of a low-mass star at the end of its life. When the Sun becomes a white dwarf, it is expected to be about as big across as two Earths.
What is a White Dwarf?
200
A group of stars within the main disk of a galaxy, containing a few dozen to a few thousand member stars, all of whom were born in roughly the same place at roughly the same time. Another name used for such a group is galactic cluster.
What is Open Cluster?
300
The name for the process of protons colliding forcefully
What is Nuclear Fusion?
300
True or False: All red giants eventually resolve their moment of crisis, finding a new source of fuel for fusion, but the star is never quite the same again.
True
300
The massive star's core becomes composed of the element ____, which sets off a final collapse and catastrophe.
What is iron?
300
The remnant of a massive star that has exploded at the end of its life as a supernova. These remnants are very dense, because the violence of the star's death has compressed them until electrons and protons have merged to become neutrons.
What are Neutron Stars?
300
The galaxy of stars in which the Sun and the Earth are located; one of the two large spiral galaxies in the Local Group.
What is the Milky Way Galaxy?

True or False: The core of every star never runs low on nuclear fuel.
False, every star eventually runs low.
400
Helium, carbon, and oxygen all serve as ______ for the stars core.
What is fuel?
400
An explosion that occasions the "death" of a massive star (or, in other cases, signals that a white dwarf in a double star system has re-ignited because a companion star has dumped a critical mass of fresh material onto it.)
What is a Supernova?
400
Constellation the zeus swung into the sky.
What is Ursa Major/Minor?

Most stars are born in groups, called ____ ______.
